100 items are made 80 of them break within five years 10 more within ten years 8 more within twenty years

Now there are two out of one hundred that are still working today, the person who owns one posts about how high quality and long lasting it is. It isn't, it's just lasted longer.

Survivors bias generally correlates to like, old people saying "back in my day nobody died of XYZ" because they didn't know anyone who died of it, that meant it didn't exist" etc,.

But it generally reders to, in this context, something made that just happened to last forever but it was an outlier, being praised as if it was the standard.
